The Littlest Doctor

If you have a paroxysmal tachyarrhythmia don't take caffeine pills.

Hypothetically speaking, you could decide to start taking them so you can have more energy for the holiday you've saved up for a long time to afford. And 3 days into your holiday, you might end up in hospital for 3 days before being discharged to go back home, your long awaited holiday ruined.

That'd suck. Hypothetically.
